HERMANN H. YOUNG, OF SAN FRANCISCO, CALIFORNIA.

DOUGH-RAISING AFPARATUS.

Application led March 13,

To all wlw/my it may concern.'

Be it known that 1, HERMANN H. YOUNG, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Dough-Raising ripparatus, et w lich the following is a speciiication.

My invention relates to bakery apparatus, in general, and, particularly, to a means for mechanically handling and disposing of the divided and rounded dough-lumps, durinT a brief raising interval, prior to molding heminto loaves ready for the ovens. After the dough is divi led into lumps oi given weight, and the lumps are rounded, to smooth out and heal, as it were, the surface cut and rounded by the divider, so that it can properly coniine the gases oi ierinentation and eitect the raising, an interval, more or less brief should be allowed before molding, to permit the necessary fermentation to take place. li this done, as would be most natural, by simply placing the rounded lumps upon tables, and allowing them to remain there any given length et time, there would result several disadvantages, such as the taking up o'l a large, available and otherwise useful space in the bakery, the handling of the material with the consequent danger oi contamination, and the cost ot labor to do the work.

To obviate these disadvantages, as well as to eilect direct beneficial results, suc-n as a more even temperature, freedom from drafts, and a control of the time of the raising inter val, are the objects of my invention; and to these ends my invention consists in the novel self-handling or automatic dough-raising apparatus which l shall now fully describe by reference to the accompanying drawings in which- Figure 1 is a plan, partly broken, oi' my apparatus. Fig. 2 is an enlarged sectional view at the entrance end of the apparatus. Fig. 3 is an enlarged side view, broken, of the raising chamber, showing its relation to the molding machine.

l indicates, somewhat diagrammatically, a dough-divider or weigher, and, similarly, 2 indicates a rounding machine, both being Specification of Letters atent.

common in the art, and, therefore, requiring no detailed description.

3 is a short, traveling belt by which the divided lumps of dough are conveyed from the divider 1 to the rounder 2.

From the delivery terminal ci' the rounder entends an endless, traveling belt l which leads upwardly at an angle to a receiving hopper 5 in the upper part of the raising chamber 6. The belt E is inclosed by a suitable casing 7 w h joins the chamber 6.

The dough lumps, when delivered by the rounder 2 to the initial belt 4, at once meet with a presser roll 8 under which they pass, with the eiifect oiC suiiiciently attening their under sides, to prevent them trom rolling on the inclined belt, and to enable them to cling thereto and to be carried up the incline. This presser roll 8 is an adjustable one, in order to properly set it with relation to the dough-lumps and with regard to their size; hus, for one pound lumps, the roll 8 will be set lower down, while if two pound lumps are being passed through, it will be raised. For this adjustment the spindle 9 ot the roll S is mounted in a slot 10, Fig. 2, in its trame, and is carried by a yoke 11 which is raised or lowered by a hand-screw 12. The presser roll is driven by a belt 13.

In the raising chamber 6 is a vertical series of horizontal, endless, traveling carriers, in any suitable number, tour being here shown. The uppermost carrier 1li is arranged to receive the dough-lumps die rectly troni the hopper 5 to which the lumps are delivered by the inclined initial belt 1; and said upper carrier thence conveys them from the hopper throughout a long hori- Zontal path to a hopper 15 at the end of said path, through which they fall 'upon the next carrier 16. By this carrier they are conveyed on a return path to a hopper 1.7, through which they fall to the third carrier 18. @n this carrier they are moved forward again to a hopper 19 through which they pass to the fourth carrier 20, by which they are conveyed b ack once more to a discharge hopper 21. By this hopper they are delivered to a molding machine, indicated by 22. The several carriers are driven, in their respective courses, by driving belts and pulleys, suitably arranged, as indicated, and which need no detailed description; and said carriers are kept under prope-r horizontal tension, by the screws .2:3 cennected. by stirrups 24 With the terminal drums of said carriers, and operated by hand-nuts 25,

as shown clearly in Fig. 3.

.The temperature in the raising chamber may be kept properly, and under suitable control, and means may be provided to permit inspection of the interior of the chamber.

It will now be seen that by my invention,

the formed and rounded dough-lumps are delivered mechanically to the raising ehamber, and are not touched by the operators. This, from a sanitary standpoint is most desirable. It will also be seen that during the interval of raising, the dough is out of the Way, instead of being spread around on tables and occupying otherwise available room in the bakery. lVhile thus disposed of in the raising chamber, the dough is subjected to its proper period of fermentation, under the most advantageous conditions of temperature, time of seclusion and proteci comprising dough lump forming and rounding mechanisms, loaf molding mechanism, and an intermediate raising chamber comprising an incased traveling carrier, all associated and connected for joint operation,

means for conveying the rounded dough lumps from the rounder to said carrier, and means for delivering the raised lumps from said carrier to the loaf molding mechanism.

In testimony Whereoil I have signed my name to this specification in the presence of two subscribing Witnesses.
